It's been quite some time since we've had cable tv here at the apartment. Translate that as, "The cable bill hasn't been paid since the 20th century." Anyhow, I've almost gotten used to not watching tv, and I seem to get a lot more done on the computer. I got bored the other night and started coding up my own implementation of DES in java. It still has a two major problem areas, encrypting and decrypting, but once those are worked out I'll try to post it up here for any interested in such things. I actually have a nice little collection of small java utils that I'll try to organize. I would like to put together a collection of java implementations of common unix commands so I can quickly add functionality to any Windows(TM) machine I may have the misfortune to have to work with. Think quick-and-easy Cygwin with java.

There is some funky mathematical property of the cryptosystem that makes a certain sizable percentage of the keys really easy to figure out. Wish I could find links to the stuff now....but if you look up NSA, DES, and leaf fields you might find something?
